01 AYD Returns & ExchangesShopify public app App development Live
AYD Returns & Exchanges, live on the Shopify App Store, is a multi-tenant Shopify public app for self-serve returns, exchanges, gift returns and store credit via a Theme App Extension. A rules engine approves, holds and refunds returns, and a prepaid Royal Mail label and QR code are sent on approval. Merchants run it all from an embedded Admin app built with Shopify's Polaris web components, with Shopify Flow, Sidekick, staff roles and a returns API on the top plan.

Building AYD Checkout Rules & Upsells, a multi-tenant Shopify public app for checkout rules, discounts and upsells. Merchants block checkout with custom messages, hide or rename shipping options, reorder payment methods, and create tiered, buy X get Y and free shipping discounts, all on Shopify Functions and set up from 60+ templates. Checkout UI extensions add banners, thank-you page offers and, on Shopify Plus, upsells.

Built a custom Shopify Hydrogen storefront serving three security-industry brands, Professional Security, Armatus and Bridgegate Security, from one shared Shopify backend. Each brand resolves from its URL path, swapping header, footer and theme per brand. Also built a restricted trade ordering channel, a pay-in-full vs. pay-in-instalments toggle with no third-party app, and a monthly auto-rotating employee password gate.

Designed and built Dip and Doze's new bespoke Shopify store from the ground up: dedicated landing pages with dynamic sections and blocks rendered through metaobjects and metafields, giving full control over layout. The product form supports dynamic variant-level add-on products, plus size and colour siblings for easy cross-navigation between related variants. Sale automations, also powered by metaobjects, update the whole site for the exact time period of a sale.

Designing and building the Behrens Group's enterprise website from the ground up: a fully bespoke build with multiple landing pages for the group's different businesses, all managed through a custom-built admin panel that lets content be updated without touching the source code. Built from scratch with React and Tailwind CSS, hosted on Cloudflare Pages for complete control over performance and architecture, with blog publishing and form submissions handled through Cloudflare Workers.
06 WPBSAOfficial Snooker Store & phone app integration Shopify 2.0 + app Live
Designed and built the Official Snooker Store for WPBSA on Shopify, connected to the ERP for orders, inventory and fulfilment. I also built a real-time single sign-on bridge between the store and WPBSA's new Play Snooker app, so app users shop without logging in twice. A custom API syncs PlayPlus membership status the instant it changes, applying the 10% subscriber discount, replacing a $149/mo app that only updated status at login.

Built and maintain multiple storefronts, including The Hybrid Games, Valor, Sale Sharks, The Sugar House and LUSU, all hosted on a single Merch Team Shopify store. Each one looks, feels and functions like a fully independent store, with its own theme, custom sections and logic (all of them run their own custom cart flows), while session handling keeps shoppers locked to the storefront they landed on. Every storefront still syncs back to the same ERP behind the scenes.

Trusted by teams at
A selection of the organisations I've helped build and run their Shopify stores.
Ali has worked with me for many years, delivering reliable end-to-end Shopify solutions. He combines strong technical development skills with a practical, solutions-focused approach, quickly understanding client requirements and finding effective ways to overcome challenges. He is dependable, creative in his execution and consistently delivers to a high standard.
Working with Ali has been an absolute pleasure. He is an exceptionally talented developer who approaches every element of a project with expertise, creativity and a genuine determination to find the best solution. No request ever feels too complicated, and there is nothing I have asked for that he hasn’t been able to achieve. He is incredibly knowledgeable, reliable and easy to work with, and his attention to detail always gives me complete confidence throughout every project. I couldn’t be happier with the recent website Ali created for us, and I would wholeheartedly recommend him to anyone looking for a brilliant developer who can turn even the most ambitious ideas into reality.
Working with Ali Hassan on the development of the new Fullerton Group uniform website has been an outstanding experience. His talent, dedication, and attention to detail have been evident throughout the entire project.
Ali has successfully created a modern, user-friendly platform that not only represents the Fullerton Group brand professionally but also allows each individual company within the group to maintain its own identity and branding. This has given us the best of both worlds: a unified system with distinct brand experiences for our employees.
The new returns and exchanges system is particularly impressive. The process is seamless, intuitive, and mirrors the experience you would expect from leading online retailers such as ASOS, making it incredibly straightforward for our employees to exchange or return uniform items. This improvement alone will save significant administrative time while providing a much better user experience.
We have been genuinely amazed by Ali’s hard work, technical expertise, and ability to turn our requirements into a solution that exceeds expectations. The speed, functionality, and overall quality of the website are exceptional, and we could not be happier with the end result. We would highly recommend Ali to anyone looking for a talented developer who consistently delivers innovative, high-quality solutions.
